A question about temperature, plants, or energy can lead to a simple experiment or a careful observation. Science trivia works best when you pause to think about what evidence might support an answer. At this age, kids can connect facts across subjects. Pause after a surprising answer to ask what they already knew and what the explanation adds.
If an answer is unexpected, ask what you could observe or test to understand it better. A new science question can be the start of a home or classroom investigation. The sample questions above give you a quick look at the subject before you start. You can also take a different category quiz if another interest catches your eye.
